Color parameter in query string ?

[paper67]

I'm calling and aspx page with a color param. I need this color to be passed on the querystring, so I call the aspx as: somepage.aspx?color=#FFFFFF&... The color parameter in the querystring is set by ColorTranslator.ToHtml(Color) I think here the problem is the # symbol. Is there a problem passing # as a parameter? How can i get back my Color object from this querystring ? I tried : if (!string.IsNullOrEmpty(Context.Request.QueryString["color"])) Color = ColorTranslator.FromHtml(Context.Request.QueryString["color"]); but for some reason the above if statement evaluates to false. How can I fix this ? TIA

This seems to work:

protected void Page\_Load(object sender, EventArgs e)
{
    String Color;
    if (Request.QueryString\["color"\] != null)
    {
        Color = Request.QueryString\["color"\];
    }
} 

protected void Button1\_Click1(object sender, EventArgs e)
{
    String URL = "Default.aspx?color=" + Server.UrlEncode("#FFFFFF");
    Response.Redirect(URL);

}

Evaluates to false ? Did you put the QueryString correctly. Use HttpUtility.UrlEncode before sending the color code. And after fetching use HttpUtility.UrlDecode to get the color code back properly.
